In the wake of those "ridiculous" cheating rumors surrounding the Focus costars, the 45-year-old actor and the 23-year-old Australian actress got together to promote their new movie at a press conference in Buenos Aires, Argentina, on Wednesday, Nov. 20.

Both looked to be in good spirits as they happily smiled and posed for pics with each other.

While Smith sported a yellow sweater and black jeans, Robbie was decked out in a pair of white pants and a sleeveless black blouse.

Earlier this month, a source told E! News that there was no truth to a Star cover story claiming that Smith, married to Jada Pinkett Smith since 1997, had a flirty photo booth session that maybe led to something more with Robbie.

The report stemmed from photos—that were duly splashed on the tabloid's cover—of the duo hamming it up in the booth.

"These pictures were commissioned by production. The entire cast and crew saw them taken," our source said. "The photo booth was on set all day for a bit of fun. It wasn't even a party—they were taken during the day and everyone knew about them. It was the last day of shooting."

The source added: "Will and Margot are absolutely just friends, that is all."

Robbie herself took to Twitter on Nov. 7 to set the record straight as well, writing, "Been working non-stop, just catching my breath. There's absolutely no truth to the ridiculous rumor in Star mag."

In Focus, which was shooting in New Orleans, Robbie plays an impressionable woman who gets caught up—and then becomes romantically involved—with Smith's veteran grifter. Kristen Stewart was previously attached to the role, but she dropped out due to scheduling conflicts.
